Résumé

Balmat pyrite standard (Whitehouse and Fedo, 2007; Marin-Carbonne et al., 2011) is known to have variable δ56Fe values (Xu et al., 2022). We have recently reanalyzed the batch of Balmat standard from UNIL (hereafter called Balmat-UNIL) at the University of Chicago (courtesy of Dr. Rego and Prof. Dauphas, unpublished data). The δ56Fe bulk value of Balmat-UNIL pyrite used in this study is −1.459 ± 0.024 ‰, compared to the previous published value of −0.399 ‰ (Whitehouse and Fedo, 2007). As all the SIMS data are standardized to the Balmat-UNIL pyrite, the correction with this new value led to a shift of 1.06 ‰ of the entire published dataset. This corrigendum presents the corrected pyrite Fe isotope data, now displaying variations between −3.05 ‰ and + 4.33 ‰. Most of the figures (Fig. 3, Fig. 4, Fig. 6, Fig. 7, Fig. 8, Fig. 9, Fig. 10, Fig. 11), and the supplementary data (Figs. S3, S5, S6 and Table S9) need to be modified as presented below. As a result of this shift, we also propose hereafter an alternative model to explain the δ56Fe signal of pyrite precipitated in the inner ramp system (section 4.3.1 - discussion), combining petrographic observations and both pyrite S and newly corrected Fe isotope results. The authors would like to apologize for this mistake.
